Hey Guys, I did an oil change on my 02 WRX a couple weeks ago. This is the second oil change since I bought the car and I decided to put semi synthetic 5w-30 instead regular mineral oil. I noticed some oil spots on the ground here and there and found that the oil was coming from a part of the car that I am unfamiliar with. Anyone know what this is from the picture? Is this a common problem on WRX's?
